Description (last modified by )
Hi,
We have been using Boost library in the project. I've made analysis by using Valgrind tool to be able to find possible memory leaks. According to the result, there is a memory leak in Boost library.
==7535== 24 bytes in 1 blocks are still reachable in loss record 2 of 6 ==7535== at 0x4C2B0E0: operator new(unsigned long) (vg_replace_malloc.c:324) ==7535== by 0x4E430A3: boost::detail::make_external_thread_data() (in /usr/lib/x86_64-linux-gnu/libboost_thread.so.1.55.0) ==7535== by 0x4E433DB: boost::detail::add_new_tss_node(void const*, boost::shared_ptr<boost::detail::tss_cleanup_function>, void*) (in /usr/lib/x86_64-linux-gnu/libboost_thread.so.1.55.0) ==7535== by 0x4E4408C: boost::detail::set_tss_data(void const*, boost::shared_ptr<boost::detail::tss_cleanup_function>, void*, bool) (in /usr/lib/x86_64-linux-gnu/libboost_thread.so.1.55.0) ==7535== by 0x54CAC0C: boost::log::v2_mt_posix::core::add_thread_attribute(boost::log::v2_mt_posix::attribute_name const&, boost::log::v2_mt_posix::attribute const&)
It seems like the allocated memory is not deallocated, so it causes memory leak. Here is the definition of relevant event ;
thread_data_base* make_external_thread_data() { thread_data_base* const me(detail::heap_new<externally_launched_thread>()); me->self.reset(me); set_current_thread_data(me); return me; } thread_data_base* get_or_make_current_thread_data() { thread_data_base* current_thread_data(get_current_thread_data()); if(!current_thread_data) { current_thread_data=make_external_thread_data(); } return current_thread_data; }
I've made some research if there is any post which states that this event causes memory leak, but could not find any. Is there any fix for the problem stated above? If there is any, could you please state the relevant patch ?
Thanks in advance,
Kind Regards
